We established a green cogeneration of high purity of zinc glycerolate(ZMG) and glycerol carbonate(GC) by using glycerol.Through just one pot, we synthesized impure zinc glycerolate first. And then we continued to synthesize glycerol carbonate. During this moment, the zinc glycerolate acted as a catalyst for glycerol carbonate synthesis and the process promoted the purity of zinc glycerolate. After the reaction, put some precipitating agent and the zinc glycerolate was precipitated. The purity of zinc glycerolate was above 97%.After the separation of the liquid mixture, we got glycerol carbonate which the purity above 97%. We discussed the product’s structure based on FTIR、XRD and elemental analysis as well. After all, the cogeneration provided a means to give a high-value conversion of glycerol and had broad application prospects.
